Summary: As to why Bose decided to leave off the most basic electronic feature known - the status light - beats me. Since it is usually one thing or another why there is no sound i.e., mute, volume, AC connection, a simple cheap common LED status light would come in pretty handy for a quick troubleshooting. The sound quality is very good but there are far better designed computer speakers for the same money.
Summary: Post card version: I went and bought a 2nd pair of these at [...] , to see if the 1st ones were defective. AND they both sounded like something from the 70's. Muddy,Dull,Bass rattle. This is after I went and bought another Battery back-up surge protector, and a program to install and upgrade drivers, registry and etc. I fixed the problem by taking back both pairs, and purchasing a pair of CREATIVE SPEAKERS M40's. [...]These have 3 knobs, volume, Bass, and a Treble.
